Why Border color and style in Tailwind? - Purpose & Use Cases

The Big Idea

What if you could change your whole site's border look by editing just a few class names?

The Scenario

Imagine you want to make a button stand out by adding a colored border. You try to write CSS for each button, setting border colors and styles manually.

  border: 2px dashed red;
}

✓ After
